    Description

      My most recent re-production of this was:
      ZFS based on 0.7.0 RC4 fs/zfs:coral-rc1-combined
      Lustre tagged release 2.9.57(but 2.9.58 fails as well)
      Centos 7.3 3.10.0-514.16.1.el7.x86_64

      I have personally verified this fails on Lustre 2.8, 2.9 and latest tagged release, zfs 0.6.5-current ZOL Master and the most recent Centos 7.1, 7.2, and 7.3 kernels.

      This may well be a Lustre issue I need to try to reproduce on raidz, with out large RPCs, etc.

      On both the clients and OSS nodes we see checksum errors while the file aging test is running such as:
